Main features:

Energy sources MultiJack provide operation of sparker and boomer sound sources that are used in geophysical surveys in the water area with Continuous Seismoacoustic Profiling (СSP), High Resolution or Ultra High Resolution Seismics (HRS/UHRS) and VSP. In addition to supporting the standard mode of operation with a single source, MultiJack energy sources allow to work in an array for successful fulfilment of the latest technologies:

Flip-flop mode

Multi-level source

Simultaneous source

Coded shooting.

The use of multilevel sources allows to achieve a certain source directivity, to control the spectral composition of the generated signal and to modify the pulse shape (the source signature). The application of multilevel sources in conjunction with impulse-code sequences makes it possible to use a ghost wave as a source of useful signal. The use of code sequences also makes it possible to work with amplitudes of generated signals that are much smaller than the source signals amplitudes in a standard seismic survey with a single excitation of the signal at each shot point. At the same time, the total energy of the recorded signal is preserved without loss in data quality.

Deploying the simultaneous source (or multi-shooting) technology allows to get a number of significant advantages in comparison with use of single sources:

Increase in the detail of research by using several nearby sources

The possibility to determine kinematic and dynamic characteristics of geological medium at depths exceeding the length of recording system

The transition from swathe shooting geometry to in-line shooting geometry due to source separation on either side of the recording system

The acquisition of seismic data over a wide range of azimuths due to non-longitudinal towing scheme of several sources

An important feature of MultiJack system when working in an array is its exceptional simplicity - all units are controlled by a single MultiJackPad remote control that allows to configure the operating mode of each energy source including determining the interval between shots and their energy, indicating the constant and accidental response delays, generating code sequences, charge rate adjustment (power consumption) and testing of the entire system or each individual unit. In addition, MultiJack energy sources are balanced by the maximum pulse energy and charge rate so that it is guaranteed to provide standard observation steps at a typical vessel speed of 3-5 knots.

The standard set of MultiJack energy source consists of:

MultiJack Unit

Sync connector (2 pc.)

Power cable

Universal switching module for connecting the source

Documentation Kit.
